Online behavioral advertising poses a real privacy threat due to its reliance on sophisticated and opaque tracking techniques for user profiling and subsequent ad targeting [1]}, [2]}, [3]}, [4]}, [5]}, [6]}.
The tracking information compiled by data brokers for the sake of online behavioral advertising is often outright creepy and scarily detailed [7]}, [8]}, [9]}, [10]}.
Furthermore, the surveillance capitalism business model of the “free” web naturally aligns with mass surveillance efforts by governments [11]}, [5]}, [13]}, [14]}, [15]}.
Finally, beyond privacy, the targeting capabilities of online behavioral advertising are routinely abused for discrimination [16]}, [17]}, [18]} and manipulation [19]}, [20]}, [21]}, [22]}.
